Installing AVG Firewall - What protocols should I allow?
Posted on 2006-10-30
I am installing the AVG Internet Protection Firewall as part of their new Internet Security 7.5. I’m actually testing it to see if it would be good for my customers, many of whom know little about computers and want to know even less – so programs that are easy to use is very important. These are not businesses for the most part, but home users. Some run small home offices. I am also going more and more toward working on client’s computers remotely using Symantec’s PC anywhere.
At the beginning of the installation it goes through your computer and marks what functions, applications and protocols it thinks it should or shouldn’t allow access to the Internet. On my computer the ones it’s marked to limit access are: Ident service, Internet Connection Sharing, L2TP VPN, Microsoft File Sharing and Printing, Novell Netware Client, PPTP VPN, Protocol AH (authentication header), Protocol ESP, Protocol GRE, Remote Administrator 2, Remote Desktop Server, Replies on ICMP diagnostics, Web Server Apache 2, Windows RPC Service.
My question is whether or not I need any of these to have access to the Internet and whether or not my clients will need any of these to have access to the Internet, especially if I use Symantec PC Anywhere. I also need to update my own web site using ftp95pro.
